I have a 93 jeep grand. Recently the trans started like sliping or won't shift.
I changed fluid and screen and added lucas.
Now it has issues changing gears, sometimes it will shift from 1 to 2 but not 3 unless I treat it like stick and let up on the gas and go to nutural and back to drive and it shifts perfect. Sometimes I can just play with the pedal and it will shift or it may automatically go from 3 to 2 while driving. I think it's the linkage or a sensor. Help

What fluid did you use to refill the trans? How long was it slipping before you changed the fluid & filter?

I used the atf +4 and it use to hesitate every one in a while in the ice.
But it only slipped for 1 day and when I got home it did not want to go in gear at all, then the next day I changed fluid and filter and added lucas. Not I can drive it but I have to play with it to get it to shift I just got home and it needs help changing from 2 to 3rd its like it just goes to 2nd while I'm in 3rd and I have to go to N and back to D and its okay for about 9 -15 min on the freeway while in 3rd.

It honestly sounds like you've got much bigger problems than just the fluid. Are any of your indicator lights on?
